About PubChem

Overview


PubChem is the National Library of Medicine’s open chemistry database and the largest freely accessible database of chemical information. Because it is “open”, anyone can supply data and anyone can access it.

PubChem data comes from over 850 sources, including academic labs, governmental agencies, chemical supply and pharmaceutical companies, journal publishers, and individual researchers. New data is added to PubChem frequently.
